Milestone:  To Be Determined  |  Component:  GIL

 line 204 in boost/gil/channel_algorithm.hpp
 if (src > unsigned_integral_max_value<uintmax_t>::value - div2)
 gives me this error with clang
 error: non-type template argument
       evaluates to -1, which cannot be narrowed to type 'unsigned long'
 [-Wc++11-narrowing]
 struct unsigned_integral_max_value : public
 mpl::integral_c<UnsignedIntegralChannel,-1> {};

 can you just replace with std::numeric_limits<unitmax_t>::max()?
